In an ancient tale, a majestic castle once graced the summit of Tihany Mountain, where dwelled the wealthy yet blind Prince Rohan and his two daughters, Horka and Helka. Horka, the elder, possessed beauty marred by wickedness, while Helka radiated kindness. Despite their differences, suitors sought their hands, only to be deterred by Horka's harsh voice. Desperate for suitors, Prince Rohan offered half his kingdom to anyone who could improve her voice. Many attempted, including Thuz herceg, but to no avail. Eventually, a fairy emerged from Lake Balaton, offering to cure Horka's voice with a magic ring in exchange for a lock of Helka's golden hair. Thuz succeeded, but reneged on his promise to return the ring to the fairy. Upon Kelén's arrival to reclaim the stolen ring, he was scorned and dismissed, finding solace with Helka. To their surprise, true love blossomed between Helka and Kelén. Learning of her sister's treachery, Helka conspired with Kelén to claim the kingdom from Horka. Consumed by jealousy, Horka and Thuz sought dark magic to eliminate their rivals. Yet fortune favored Helka and Kelén when they saved the life of a benevolent wizard, who transformed the wicked couple into a crow and a wild boar, and in gratitude for their kindness, restored Prince Rohan's sight. Thus, they inherited the kingdom and lived happily ever after.
